I haven't tried the 410's but I have tried the 385's and did not get as good of results as with the 460 NE's and BS's. I do like shooting those big conicals but I'm out of them right now so I'm going with the 300 SW's.

I'm not that worried about the fps as long as it's similar to what I get from other powders. The problem I have with a powder that costs as much as 777 yet needs 30 to 40% more powder to achieve similar performance is it ends up costing 30 to 40 % more to shoot. I get good to very good accuracy from several powders so why pay more for less.
